Cable System Facts

Performance

Since the Network Ready for Service Date of December, 2001, the AJC network has incurred 3 submarine faults. This number of faults is in line with industry expectations for such a cable network. In all three cases, the repair operations were completed in about 7 days utilising the contracted cable ships.

During the repair operations, the protected transmission services continued to operate as designed, with traffic routed on the alternate network path. The AJC Network is monitored on an ongoing basis by the AJC NOC and the landing stations.

The AJC Network is monitored on an ongoing basis by the AJC NOC and the landing stations. The optical transmission performance of the AJC network continues to meet the relevant industry standards for performance and availability. The network has been successfully upgraded from the initial installed 10G technology to 100G technology in the latest upgrade in 2013/2014.

Bit Error Rates better than ITU-T Rec G.826/828 with associated Q-Factors stable and with good end of life margin.

The figures of 36msec Sydney-Guam, 20msec Guam-Japan and 56msec Sydney-Japan are as expected for these distances. ITU-T Recs Y.1541 and Y.1542 indicate that latency in the terrestrial components of a User to User connection largely subsume differences in the international component.
